How does LAST Preservative work, chemistry-wise?

An amalgam of polyvinyl chloride and polyvinyl acetate is used for manufacturing records. These are relatively long chain molecules. Under sufficient magnification, they resemble a pile of “Lincoln Logs”. As such, there are numerous small voids, pits, and crevasses. The active components used in LAST Record Preservative have (1) a strong affinity for vinyl, and (2) a very small size compared to the vinyl molecules. The Preservative enters and “locks into” these voids, thereby acting as a permanent shock-absorber for the vinyl. The benefits of longer life, lower distortion, and noise floor are all brought about by the characteristics of affinity for vinyl coupled with the tiny size of the Preservative molecules.
